To a whom, it may concern:

Be it known that we, RUFUS H. BENNETT and WARREN Rosco MOREY, citizens of the United States, residing at Iola, in the county of Allen and State of Kansas, have invented a new and useful Crude-Oil Burner, of which the following is a specification.

Our invention relates to improvements in apparatus for burning crude petroleum and other inflammable oils for heating purposes, whether domestic or otherwise.

The accompanying drawing represents a face elevation of our burner with opening in the hot-air chamber to showthe feed-pipe, and opening in the hood to show the discharge-orifice of the feed-pipe, and opening in the pipe inclosing the feed-pipe to show the asbestos wrapping and feed-pipe within, also showing lock-nuts fastening the feedpipe to the side of the fire-box, with asbestos washer to make chamber tight at the top, also showing the movable cup at the bottom of the chamber with the manner of fastening same by hooks or fingers with notches which work on the rim on the outside of the chamber and showing the aperture between the cup and chamber.

. The apparatus, as shown bythe accompanying drawing, consists, primarily, of a vertically-arranged iron pipeA for a hot-air chamber, with the upper end closed and lower end open and supporting the movable cup B. The

oil-feed pipe a a a penetrates this chamber at or near the top and through which the oil (fuel) is fed into the burner, the supply of which is "regulated by means of avalve in said pipe between the fire-box and supply-tank. The orifice of this pipe is so placed that the oil will drop straight down through the center of the hot-air chamber and is held in place in said chamber by the lock-nuts (Z (Z on either side of the wall of said chamber where the.

feed-pipe enters, and on the upper or face side of the inner lock-nut is placed an asbestos washer f, which serves to render the top of the chamber air-tight at the opening admitto the wall of the fire-box by the lock-nuts (Z (Z, placed upon said feed-pipe or outer pipe on either side of said fire-box where said feedpipe enters at 0. The discharge-orifice of the feed-pipe within the chamber bis projected through the bottom of an inverted metallic cup or cap c,- forming a hood with sides eX- tending around and below said orifice to protect it from excessive heat of the burning oil and to prevent the accumulation of soot or other residuum upon or about said orifice. Near the bottom of the chamber a flange 76 extends around it, divided into three equal segments, between which are admitted the fingersZ Z, which support on said flanges the metallic cup B by means of notches in said fingers which work upon said flanges. These flanges are so inclined to the surface of said chamber that by turning the cup the aperture 0 0 between the cup and chamber is increased or diminished. The cup aforesaid may be allowed to rest upon legs 1 2 3, which hold the bottom of the cup at a fixed distance from the grate or bottom of the fire-box and tend to preserve an air-passage beneath said cup.

In the practical operation of this burner a metallic pan X is fitted to the bottom of the fire-box or set upon the grate, made by riveting together two pieces of sheet-iron, with a sheet of asbestos between, and the bottom of the pan is covered with a thin layer of sand or ash for convenience in cleaning. The fueloil is then allowed to overflow the cup and run into said pan, where it is burned in quantity sufficient to heat the chamber, and when so heated the fuel-oil is dropped through the hot air in the chamber from the feed-pipe, is Volatilized, and burns out through the opening between the chamber and cup and up and around said chamber, keeping it constantly hot. The flame may be spread in the fire-box at will by turning the cup upon the flanges so as to decrease the aperture between the cup and chamber. Any unvolatilized oil is deposited in the cup at the bottom of the chamher, where it is supplied with hot air, and uninflammable matter is removed from the cup when cold.

What we claim is 1. In an oil-burner, the combination of a vertically-arranged cylinder open at its lower end and closed atits top, with an oil-feed pipe penetrating the top of the casing and secured thereto by lock-nuts, an asbestos wrapping inclosing said feed-pipe, a protecting-hood arranged on the discharge .end of such pipe, inclined flanges arranged on the lower portion of the cylinder, and a cup having fingers to engage said flanges and adjustably supported thereby below the open end of the cylinder, substantially as shown and described;

2. In an oil-burner, the combination of a vertically-arranged cylinder, open at its lower end and closed at its top, with an oil-feed pipe penetrating the top of the casing and secured thereto by lock-nuts, an asbestos wrapping surrounding said feed-pipe and an outer pipe inclosing said wrapping, a protecting-hood arranged on the discharge end of such pipe, inclined flanges arranged on the lower portion of the cylinder, and acup having fingers to engage said flanges and adjustably supported thereby below the open end names to this specification in the presence of two subscribing witnesses.
